Mahoney, Malibu, Calif. Filed Nov. 28, 1966, Ser. No. 597,3193 Claims. (Cl. 49-62) ABSTRACT F THE DISCLOSURE A main sash is mountedin a frame and has end connected rails and stiles receiving a pane in apane opening thereof. The rails and stiles ha-ve lengthwise borestherein in a common plane parallel to and spaced normal to the plane ofthe pane, and also channels from said bores opening toward said paneopening in said parallel, spaced plane. Fasteneres are received in saidbores securing said rails and stiles together, and latch plates of astorm sash in said pane opening are received in said channels and bores.

Background of the invention This invention relates to a closure withimproved storm sash fastening incorporated therein and, moreparticularly, to a closure of the type having a main sash having a stormsash removably secured thereto and covering the pane of said main sashwherein the fastening between said main and storm sash is of an improvedform permitting a greater range of glass thicknesses in the main sash.

The invention of the present application is an improvement on theclosure disclosed and claimed in U.S. Letters Patent No. 3,208,111,granted Sept. 28, 1965, and entitled, Closure With LongitudinallyMovable Sash. As disclosed in Letters Patent No. 3,208,111, the form ofclosure herein involved includes a frame mounting one or more mian sash.Where two main sash are included in said closure, one of said sash maybe an outer stationary sash and the other of said sash may be an inner,longitudinally movable sash, but in any event, each of said main sashwill include a storm sash removably secured to and covering the pane ofsaid main sash.

In the closure of the aforesaid patent, the rails and stiles of the mainsash are formed with bores lengthwise therethrough for receivingfasteners secured therein and end connecting said rails and stiles inthe required rectangular configuration. Said rail and stile bores extendin a plane parallel to, but spaced transversely from, the sash pane.Furthermore, storm sash fastening channels are formed in said rails andstiles separate from said bores in a plane parallel to, but spacedtransversely from, said sash pane a distance greater than the plane ofsaid bores, said storm sash fastening channels opening inwardly towardsaid pane.

Thus', the storm sash is received within the main sash for removablesecurement therewith and has a resilient gasket for abutting and sealingagainst the main sash pane. A plurality of pivotal latch blades aremounted on the storm sash for selective engagement in the main sashfastening channels, thereby securing the storm sash to the main sash.

By combining in the present construction the functions of the latch andsash fastener receiving bores and channels, the extrusions constitutingthe sash have been reduced in weight. Furthermore, a greater range ofglass thickness is receivable in the sash without increasing thetransverse cross-sectional dimensions of the sash.

Objects and summary of the invention It is, therefore, an object of myinvention to provide a closure with improved storm sash fasteningincorporated therein whereby the transverse dimensions required forPatented Nov. 19, 1968 ice the storm sash fastening in the main sash arereduced to thereby reduce the material of the main sash and permit agreater range of main sash glass thicknesses. According to the presentinvention, the storm sash fastening channels of the rails and Stiles areformed in the same plane and opening into the rail and stile fasteningbores so that the main sash may be formed for receiving glass of greatertransverse thickness without increasing the overall transverse thicknessof the main sash.

It is another object of my invention to provide a closure with improvedstorm sash fastening incorporated therein whereby not only is areduction in main sash material and permissible increase in glassthickness obtained, but the storm sash may be removably received in andSecured to the main sash in virtually the identical manner heretoforeprovided. The storm sash is, therefore, provided with the same form ofpivotal latch blades selectively received in the main sash fasteningchannels to secure the storm sash with the main sash.

Other objetos and advantages of the invention will be apparent from thefollowing specicaiton and the accompanying drawing which is for thepurpose of illustration only, and in which:

Description ofthey best embodiment contemplated As hereinbefore stated,the closure with the improved storm sash fastening incorporated thereinof the present invention constitutes an improvement in the closureconstruction set forth in the prior Patent No. 3,208,111, said improvedstorm sash fastening being incorporated in said prior construction. Forthis reason, the details of the overall closure are only brieflydescribed herein t0 the extent necessary to understand the overallworking relationship between the frame, the stationary sash and thelongitudinally movable sash, with said prior patent being referred tofor a more complete description of said closure. There are certainstructural changes in the closure and sash shown herein from those ofsaid prior patent which are not of importance to the improvements of thepresent invention, but the overall construction an operation of theclosure shown herein will be clear from a complete understanding of saidprior patent.

Referring to the drawing hereof, a closure, generally indicated at 10,is generally rectangular in inward and outward appearance and includes aframe 12 having a header 14, a sill 16 and longitudinally spaced, sidejarnbs 1S, said jambs maintaining the header and sill in operative andspaced relationship in the usual manner. Furthermore, the header, silland jambs 14, 16 and 18 co-operate to forwardly and rearwardly dividethe frame 12 into a pair of upper tracks 20 and 22, a pair of lowertracks 24 and 26 and preferably pairs of side channels 28 and 30 on eachof the jambs 18.

Viewing the closure 10 from the inner side, as shown in FIGS. 1 and 4,the lower side of FIG. 2 and the righthand side of FIG. 3, a stationaryouter sash 32 is mounted in said frame within the upper and lower tracks20 and 24 and within the side channel 28 extending longitudinally ofsaid frame and being Secured intermediate thereof by a tie bar 34. Thestationary outer sash 32 includes upper and lower rails 36 and 38maintained in operative and spaced relationship by longitudinally spacedStiles 40 and 42, said rails and Stiles appropriately enclosing a glasspane 44. The stile 42 intermediate the frame 12 is secured in the tiebar 34.

A longitudinally movable inner sash 46 is received at the right-handside of the frame 12, as viewed in FIGS. v1 and 2, within the upper andlower tracks 22 and 26 and is normally also received in the right-handside channel 30 when said movable inner sash is in closed position, asshown. The movable inner sash 46 includes a glass pane 48 appropriatelyenclosed by upper and lower rails 50 and 52, a stile normally at thejamb 18 and a stile 56 normally intermediate the frame 12 and preferablyinwardly overlying and covering the mating stile 42 of the stationaryouter sash 32. The movable inner sash 46 is mounted in the frame lowertrack 26 for longitudinal movement relative to said frame and saidstationary outer sash 32 by means of a carriage 58 supported onappropriate rollers 60, again more clearly described in said priorpatent, No. 3,208,111.

A resilient bumper 62 may be mounted on the frame jamb 18 within thechannel 30 for abutment by the stile 54 of the movable inner sash 46when said sash is moved longitudinally of the frame into fully closedposition, as shown in FIG. 2. In addition, the stiles 40 and 56 may beprovided with appropriate flanges 64 and 66 projecting from said stilesinward of the frame 12 for hand engagement in order to move the movableinner sash 46 in the direction toward its fully closed position.Furthermore, a spring biased bolt 68 of a latch 70 mounted on the stile56 is adapted for engagement in a keeper 72 of the stile 42 on thestationary outer sash 32 for locking said movable inner sash 46 in saidfully closed position.

More particularly to the improvements of the present invention, each ofthe rails 36 and 38 and the Stiles 40 and 42 of the stationary outersash 32, and each of the rails S and 52 and the Stiles 54 and 56 of themovable inner sash 46 is formed with a circular cross section bore 74extending lengthwise and the total length thereof. Said bore 74 extendsin a plane parallel to, but spaced transversely inwardly of the glasspanes 44 and 48 of said sash. Thus, the various rails and stiles may besecured end connected perimetrically defining the rectangular openingsclosed by said glass panes 44 and 48 by fastening screws 76 receivedthrough certain of said rails and Stiles and secured in the bores 74 ofthe adjacent of said rails and Stiles in the manner shown in FIG. 4wherein a fastening screw is received through the stile 40 and into thebore 74 in the lower rail 38 of the Stationary outer sash 32.

Also, a Storm sash fastening channel or slot 78 is formed in each ofsaid rails and Stiles lengthwise thereof opening into said `bores 74 andinwardly toward said sash openings or the glass panes 44 and 48. Saidstorm sash fastening channels 78 extend in the same described plane asthe extension of the bores 74, that is, spaced transversely inwardly ofthe glass panes 44 and 48. Thus, the storm sash fastening channels 78are positioned in the same plane as the sash bores 74 for fasteningtogether the sash rails and Stiles by the fastening screws 76, ratherthan said bores and channels extending in separate transversely spacedplanes, as in the closure construction of Said Patent No. 3,208,111, ashereinbefore described.

It is preferred that all of the sash, rails and Stiles will be formed asmetal extrusions, preferably aluminum, as are many of the othercomponents of the closure 10. All of the rails 36, 38, 50 and 52 of thestationary outer and movable inner sashes 32 and 46 are identical crosssection, S0 may be formed of the same metal extrusion .4 cut to properlength. All of the Stiles 40, 42, 54 and 56 of said sashes 32 and 46are, however, each of slightly dilferent crosssectional configurationand must be formed of separate metal extrusions cut to proper length,but still each including the described bores 74 and storm sash fasteningchannels 78.

A storm sash 80 is received in the stationary outer sash 32 within therails 36 and 38 and the Stiles 40 and 42 thereof. The storm sash 80 isappropriately formed with a frame 82 pivotally mounting a plurality ofspaced latch blades 84 around the perimeter of said frame and pivotal topositions in which said latch blades depend from the frame perimetertoward the sash rails and Stiles. The storm sash 80 is received in thestationary outer sash 32 at the inner side of said sash, with aresilient gasket 86 sealing against the sash glass pane 44 and with thelatch blades 84 aligned with the storm sash fastening channels 78 forpivotal slidable reception in said channels to secure said storm sashwith the stationary outer sash.

The movable inner sash 46 is similarly provided with a storm sash 88 ofthe same construction, including a frame 90 having a plurality of latchblades 92. The storm sash 88 is similarly received in the movable innersash 46 within the rails 50 and 52 and the Stiles 54 and 56. A similarresilient gasket 94 seals against the inner side of the sash glass pane48, while the latch blades 92 are aligned with and pivotally slidablyreceived in the storm sash fastening channels 78 of said movable innersash, thereby securing the storm sash therewith.

According to the present invention, therefore, I have provided a closurewith improved storm sash fastening incorporated therein having theprincipal advantages of permitting an overall reduction in the Weight ofthe sash extrusions while permitting a greater choice of glassthicknesses without increasing the transverse dimensions of saidclosure. As hereinbefore described, the bores 74 for receiving thefastening screws 76 to secure the main sash assembled and the storm sashfastening channels 78 for selectively removably receiving the latchblades 84 of the Storm lsash to secure said storm sash with said mainsash all extend in the same general plane, rather than in separate,transversely spaced planes, as in the prior constructions. As a result,the transverse dimensions of the closure of the present invention arenot increased by increased sash glass thicknesses.
